Permission denied: '/dev/ttyUSB0' ? So, how do I give myself permission?

Keep getting Permission denied: ‘/dev/ttyUSB0’ when I try and output a job to my plotter.

How do I give myself permision?

(it uses a USB to serial adaptor and I’m on KDM Plasma)

Maybe add yourself to group tty or dailout?

sudo usermod -aG tty $USER
